STREET-REPAIR MACHINE.

Application filed September Thisinvention relates to. a street repairing inachine which involves a small portable asphalt plant for preparing and laying the hot asphalt used for patching bitulithic streets, repairing brick or concrete pavements, paving railway crossings or laying mastic floors. In' the repair of bitulithic streets the asphalt is delivered to the repair site in a hot condition and sand and other materials can be hauled along with tool heaters and other apparatus. All of this requirestime and considerable labor, which my invention aims to reduce to a minimum by embodying all mechanical-and material requirements in a single vehicle machine that can be drlven under its own power or otherwise moved.

The street repairing machine includes a rotary sand drier; a sand and asphalt cement heater; an agitating mixer; storage bins for various kinds of material; measuring devices for properly proportioning an admixture of material; tool heaters and a power transmission mechanism by which the propulsion power plant of the machine may be used for operating the sand drier, mixer and other parts of the machine adapted to be power driven.

In constructing the machine thevarious parts are compactly arranged and located so that a source of heat at one part of the machine may be utilized to the fullest extent for various purposes, and provision is made for thoroughly insulating parts of the machine to conserve heat and prevent machine parts from being distorted.

The reclaiming of old asphalt during the operation of the machine is another feature because the machine includes a heater for such old asphalt, a mixer by which new material may be added to the old, and means of quickly distributing the asphalt mixture to a street for patch purposes. I

Other distinct advantages are gained by a machine in accordance with my invention and some of these advantages will appear as I describe in detail the constructive arrangement of the various parts of the machine.

Reference will now be had to the drawings, wherein-- Figure 1 is a side elevation of the operators side of the machine;

Fig. 2 is a vertical longitudinal sectional view of the same;

Fig. 3 is a side elevation of the opposite side of the machine from that shown in Fig. 1;

Fig. 1 is a view of the rear end of the mahme partly broken away and partly in sec- Fig. 5 is a cross sectional view of the machine taken on the line VV of Fig. 3;

6 is a plan of the machine, and 1g. 7 1s a cross sectional view taken on the line VIIVII of Fig. 2.

A machine in accordance with this invenvention includes a large chassis 1 having a rear axle assembly 2 including a rear axle 3 provided with a large sprocket wheel 4. The forward end of the chassis is supported from a conventional form of front axle as sembly 5 with which there is associated a conventional form of steering mechanism 6. On the forward end of the chassis is a conventional form of power plant, such as an internal combustion engine and all of its accessories necessary'for controlling and maintaming the power plant in operation, either for moving the machine about or as a source of power for driving parts of the machine when stationary at an operating site. I have deemed it unnecessary to illustrate the power plant of the machine other than to show a drive shaft 7 which'may be considered as a power take-01f shaft should the machine be built on an ordinary truck chassis.

Suitably mounted on the machine chassis 1 and supported by an ordinary spring is a large rectangular housing including a cab 8 for the driver of the machine. Directly behind the cab 8 is a vertical opening 9 afi'ording clearance for an endless chain 10 driven from the power take-off shaft 7 and adapted to drive a longitudinally disposed shaft 11 journaled in bearings 12 mounted on top ofthe housing. The shaft 11 extends rearwardly and through the medium of beveled gear wheels 13 drives a transverse shaft 14 which protrudes from the operators side of the machine.

Supported from the operators side of the housing is a revoluble shaft 15 adapted to be driven from the shaft 14 by an endless chain 16 and adapted to drive the wheel 4 by an endless chain 17. The protruding end of the shaft 14 may be provided with a conventional form of clutch 18 controlled by a rod 19 within easy reach of an operator at the side of the housing.

The elements 10 to 19 inclusive constitute a power transmission from the power take-off shaft 7 to the rearaxle 3 of the machine and by virtue of the clutch 18 power may be used for propelling the machine from one location to another or used for operating parts of the machine, as willhereinafter appear.

The rear end of the large housing has a transverse partition 20 and connecting this artition and the rear end wall 21 of the ousing is a longitudinally disposed and center casing 22 forming a tool heating compartment- 23 to receive tools 24 through an opening 25 in the end wall 21. The inner ends of the tools 24 are adapted to rest on a horizontal grate or perforated shelf 25 in spaced relation to the bottom wall 26 of the housing, so as to form a burner compartment 27. In the burner compartment are burners 28 connect-ed by a fuel supply pipe 29 to reservoirs 30 and 31 suitably supported on the end wall 21 of the machine housing. The reservoir 30 may contain kerosene or other inflammable fuel supply to the burners 28 in safe quantities. The reservoir 31 may contain a reserve supply of fuel or may be used for carrying liquid for other purposes.- The casing 22 is not spaced relative to the sidewalls of the machine housing, as best shown in Fig. 4, whereby the casing and partition 20 may cooperate with the machine housing in providing a storage bin 32 for sand or other material. Access is had'to this storage bin through a normally closed manhole 33 iii the top wall 34 of the machine housing. 1

In advance of the partition 20 is another transverse partition 35 cooperating with a horizontal partition 36 in forming a drier compartment .37 extending transversely of the machine. At the ends of this drier compartment are a series of roller supports 38 for the end annular rails 39 of a revoluble drying drum-40 adapted to be heated by burners 41 locatedinthe compartment 37 under the drum 40. A longitudinallydisposed fuel supply pipe 42 extending from the fuel supply pipe 29 communicates with the burners 41 for supplying fuel thereto.

The ends of the drying drum 40 are substantially closed with the exception of an inlet opening 43 and an outlet opening ,44. The

discharge trough 45 has its outer discharge end mounted on a rock shaft 46, journaled in bearings 47 supported from the operators side of the machine housing. A crank or handle 46 on the shaft 46 permits of the trough 45 being tilted to discharge material deposited in the trough by the rotating drum. Attached to the inner wall of the drum are agitators 48 by which quantities of the material are lifted and deposited in the trough 45.

The receiving end of the drum 40 has a large sprocket wheel 49 for an endless sprocket chain 50 trained over a small sprocket wheel 51 loose on the protruding end of a transverse shaft 52, journaled in bearings 53, carried by the top wall 34 of the machine housin Beveled gearing 54 is adapted to drive 518 shaft 52 from the longitudinally disposed shaft 11 and the rotation of the drum 40 is controlled by a conventional form of clutch 55 by which the small ear wheel 51 maybe fixed relative to the driven shaft 52.

The bottom wall 36 of the drier compartment 37 cooperates with a depressed portion 56 of the bottom wall 26 in providing a material bin or compartment 57 which may communicate with the storage bin 32 by a chute 58 extending through the drier compartment 37, see Fig. 2. At the off side of the machine the compartment 57 has a slide door 59 so that material may be easily obtained from the compartment 57 and placed in the drying drum '40 or used for other purposes. There may be a similar door 60 on the operators side of the machinehousing.

In advance of the drying compartment 37 and extending transversely of the machine housing is an asphalt tank 61 having a fill- I ing connection 62 and thenormally closed manhole 63. Spaced from this tank and in the rear of the opening 9 is a cement bin 64 having a filling connection 65 and a front insulated wall 66. The tank 61 and the bin 64 are separated by a flue 67 communicating with a burner compartment 68 under the tank 61, said burner compartment communicating with the drier compartment 37 which has a vent or flue 69. The bottom of the burner compartment 68 is formed by a horizontal wall 70 formingthe bottom of the cement bin 64 and on the wall 70 are burners 71 having a fuel supfply pipe 72connected to the longitudinal uel supply pipe 42.

Below the wall 70 and in advance of the compartment 57 is a transversel mixing receptacle 72 having a receiving chute 73 at the operating side of the machine.

Extending longitudinally of the mixing receptacle 72 is a driven agitator shaft 74 provided with a plurality of agitators 75. One end of this shaft protrudes from the off side of the machine and is provided with a large sprocket wheel 76 over which is trained an endless sprocket chain 77 operatively engaging a small sprocket wheel 78 loose on a transverse shaft 7 9 rotatably supported at substantially a right angle to the power take-ofl shaft 7. Beveled gearing 80 transmits power from the power take-off shaft 7 to, the transverse shaft 79 and a conventional form of clutch 81 controls the operation of the agitator shaft 74.

Longitudinally of the mixing receptacle 72, ad acent the bottom wall 70 and to one side of said receptacle, is a tiltable measuring trough 82 on a rock shaft 83 having a crank 84, at the chute 73, -b which the rock shaft may be turned to tilt t e trough 82 and discharge its contents into the rece tacle 72. The trough 82 receives asphalt rom the tank 81 through a faucet 85 carried by the disposed bottom of the tank and extending into an opening 86 in the bottom wall 70 above the measuring trough 82.

At the opposite side of the receptacle 72 is a rotary multiple cement measuring device 87 adapted to receive cement from the bins 64 through a discharge opening 88 controlled by a slide 89 operatable at the operators side of the machine. The measuring device 87 may be conveniently rotated by a crank 90 at the operating side of the machine.

. The bottom of the receptacle 72, intermediate the ends thereof, has a discharge spout 91 controlled by a slide valve 92 operatable from either side of the machine, see Fig. 7.

On the operating side of the machine are brackets 93 for a longitudinally disposed overhead rail 94 on which there is a traveler 95 supporting a tiltable pocket 96 adapted to receive material from the trough 45, convey the material to the chute 73, and discharge the material into the mixing receptacle 72 to commingle with other ingredients or materials within the mixing receptacle 72 agitated and mixed by the agitators 75 preparatory to passing through the discharge spout on to the pavement being laid or repaired.

The end wall 21 of the machine housing may have a slide door 97 by which quantities of material may be obtained from the bin 32.

I attach considerable importance to the arrangement of the various bins, tanks and receptacles, particularly relative to the source of heat for the tools 24, the drying drum 40 and the asphalt tank 61, because walls of the bin 32 will be heated from the tool casing 23 and heated air from this casing can enter the drier compartment 39 and from there pass under the tank 61 to the main flue 67. Materials in the bins, tanks and the like can be dried or maintained in proper condition for admixture in the receptacle 72 or' materials may be obtained from the bins for use independent of other material supplies of the machine. The portability of the machine is a feature because at large patches the mixture may be dumped and raked without intermediate handling, thus eliminating trucking and labor incident thereto. Another feature is the reclaiming of old asphalt during the operation of the machine, the asphalt being cut from the street, loaded into the sand drying drum, heated therein, agitated in the mixin receptacle, new material added if desire and returned to the street providing a marked economy in patching cost. Mechanical controls are within convenient reach of an operator, who with the assistance of a 'laborer may run the entire machine. With the bin and tanks properly proportioned there is a maximum storage capacity for all matrials necessary for paving purposes, and while in the drawings there is shown a preferred arrangement of the various bins, tanks and receptacles, it is to be understood that the arrangement ma be varied along withv the power transmission mechanism without departing from the scope of the'appended claims.

What I claim is 1. A street repair machine comprising a housing, material containers mounted in said housing and spaced from each other, a mixing device supported by the housing, and heating devices disposed under certain of said containers, whereby the heat issuing from said devices is efiective also on the remaining containers, means of communication between said mixing device and certain of said containers, and measuring feeders interposed in said means of communication.

2..A street repair machine comprising a housing, material containers mounted in said housing and spaced from each other, a mixing device supported by the housing, and heating devices disposedunder certain of said containers, whereby the heat issuing from said devices is elfective also on the remaining containers, a tool heating device spaced beneath one of said containers, the space between said heating device and container being adapted to receive tools, means of communication between said mixing device and certain of said containers, and measuring feeders interposed in said means of communication.

In testimony whereof I afiix my signature.
